The vegetable oils are one of the most perspective renewable raw materials due to bio- degradability and non-toxicity inherent them and also wide area of application. The non-edible seed oil of the Jatropha plant is a renewable and sustainable material to produce vegetable oil-based epoxy as raw polymeric material. The objective of this study is to synthesis Jatropha seed oil-based epoxy resins through conventional methods. An epoxy ring of Epoxidized Jatropha Oil (EJO) was formed through an epoxidation process using hydrogen peroxide and formic acid as an oxygen donor and oxygen carrier respectively. The physical characteristics of seed and epoxidized oil were investigated and also the oil was investigated by using analytical methods. The proximate compositions of the seeds were as follows: Moisture (4.128%), ash (3.4%) and seed density (1.4 g/ml). In addition to this, physicochemical characteristics of Jatropha seed oil were acid value (3.847 mg KOH/g, free fatty acid (1.9235 mg KOH/g). The jatropha seed oil can be suitable for the production because this give semidrying property. The epoxy oil was produced by mixing the jatropha oil, formic acid, hydrogen peroxide and sulfuric acid as a catalyst in three necked and stirred by magnetic stirrer in heating mantle for five hours. Then the product purified by washing with water.
The experiments were carried out by three-level and two-factor. A total of 9 experiments were conducted at conditions of reaction temperature 40, 55 and 70°C, volume ratio of hydrogen per oxide to oil 1, 1.5 and 2 and by taking the formic acid and sulfuric acid constant for 5 hours of reaction time.
